What Are The Causes Of & Risk Factors For Scalp Melanoma
Sun exposure is the leading cause of all forms of melanoma. Because the scalp often receives a significant amount of sun exposure, that means there is a high risk for melanoma and other forms of skin cancer in this area. In addition to sun exposure, regularly visiting tanning beds, radiation treatment, and chemical exposure can all contribute to the development of skin cancers.
In addition to the underlying causes of skin cancer, numerous factors can increase the risk of developing scalp melanoma, including:
- Taking immunosuppressive medications
What Does Melanoma Look Like
Melanoma is a type of cancer that begins in melanocytes . Below are photos of melanoma that formed on the skin. Melanoma can also start in the eye, the intestines, or other areas of the body with pigmented tissues.
Often the first sign of melanoma is a change in the shape, color, size, or feel of an existing mole. However, melanoma may also appear as a new mole. People should tell their doctor if they notice any changes on the skin. The only way to diagnose melanoma is to remove tissue and check it for cancer cells.
Thinking of “ABCDE” can help you remember what to look for:
- Asymmetry: The shape of one half does not match the other half.
- Border that is irregular: The edges are often ragged, notched, or blurred in outline. The pigment may spread into the surrounding skin.
- Color that is uneven: Shades of black, brown, and tan may be present. Areas of white, gray, red, pink, or blue may also be seen.
- Diameter: There is a change in size, usually an increase. Melanomas can be tiny, but most are larger than the size of a pea .
- Evolving: The mole has changed over the past few weeks or months.
Melanomas can vary greatly in how they look. Many show all of the ABCDE features. However, some may show changes or abnormal areas in only one or two of the ABCDE features.
How Do People Find Signs Of Melanoma On Their Own Skin
Performing a skin self-exam as often as recommended by your dermatologist is the best way. While examining your skin, you want to look for the following:
Mole that is changing in any way
Spot that looks different from the rest of the spots on your skin
Growth or spot on your skin that itches, bleeds, or is painful
Band of color beneath or around a nail
Sore that doesnt heal or heals and returns
The ABCDEs of melanoma can help you find changes to a mole, freckle, or other spot on your skin.

Basal Cell Carcinoma Pictures
Basal cell carcinoma usually appears in areas of the skin previously exposed to high levels of UV radiation such as the head, neck, ears and the back of the arms and hands. It is common in exposed skin of outdoor workers or people who have used sun tanning beds in the past.
As the basal cell carcinoma pictures below indicate, this type of skin cancer usually shows as a fleshy coloured bump that does not disappear over time and tends to grow slowly in size, eventually breaking down and ulcerating.
Below are pictures of skin cancer on the neck, face and trunk . These images show common areas where basal cell carcinoma develops, but it can develop anywhere.

How Common Is Melanoma
Melanoma accounts for only about 1% of all skin cancers, but causes the great majority of skin cancer-related deaths. Its one of the most common cancers in young people under 30, especially in young women.
Melanoma incidence has dramatically increased over the past 30 years. Its widely accepted that increasing levels of ultraviolet exposure are one of the main reasons for this rapid rise in the number of melanoma cases.

Squamous Cell Carcinoma Pictures
Squamous cell carcinoma also appears in areas most exposed to the sun and, as indicated in the pictures below, often presents itself as a scab or sore that doesnt heal, a volcano-like growth with a rim and crater in the middle or simply as a crusty patch of skin that is a bit inflamed and red and doesnt go away over time.
Any lesion that bleeds or itches and doesnt heal within a few weeks may be a concern even if it doesnt look like these Squamous cell carcinoma images.
What Are The Melanoma Stages And What Do They Mean
Stage 0 and I are localized, meaning they have not spread.
- Stage 0: Melanoma is localized in the outermost layer of skin and has not advanced deeper. This noninvasive stage is also called melanoma in situ.
- Stage I: The cancer is smaller than 1 mm in Breslow depth, and may or may not be ulcerated. It is localized but invasive, meaning that it has penetrated beneath the top layer into the next layer of skin. Invasive tumors considered stage IA are classified as early and thin if they are not ulcerated and measure less than 0.8 mm.
Find out about treatment options for early melanomas.
Intermediate or high-risk melanomas
Localized but larger tumors may have other traits such as ulceration that put them at high risk of spreading.
- Stage II: Intermediate, high-risk melanomas are tumors deeper than 1 mm that may or may not be ulcerated. Although they are not yet known to have advanced beyond the primary tumor, the risk of spreading is high, and physicians may recommend a sentinel lymph node biopsy to verify whether melanoma cells have spread to the local lymph nodes. Thicker melanomas, greater than 4.0 mm, have a very high risk of spreading, and any ulceration can move the disease into a higher subcategory of stage II. Because of that risk, the doctor may recommend more aggressive treatment.

Can Changing My Diet Help Prevent Melanoma
The American Cancer Society advocates eating a plant-based diet over an animal-based diet as part of a healthy plan to avoid all cancers. Growing evidence suggests that plants pack a powerful punch in any fight against cancer because they’re nutritious, cholesterol-free and fiber-rich.
Theres no doubt that a healthy diet can protect your immune system. Having a strong immune system is important to help your body fight disease. Some research has shown that a Mediterranean diet is a healthy choice that may help prevent the development of cancer. Talk to your healthcare provider about the role food plays in lowering your cancer risks.
Some skin and immune-system healthy foods to consider include:
- Daily tea drinking: The polyphenols in tea help strengthen your immune system. Green tea contains more polyphenols than black tea.
- High vegetable consumption: Eating carrots, cruciferous and leafy vegetables is linked to the prevention of cutaneous melanoma.
- Weekly fish intake: Study participants who ate fish weekly seemed to avoid developing the disease when compared to those who did not eat fish weekly.

Early Detection Starts With You
When caught and treated early, skin cancers are highly curable. And in the early stages of skin cancer development, youre the one with the best chance to see changes.
Thats why we recommend that you examine your skin head-to-toe every month. Its a simple but powerful way to look at yourself with a new focus that can save your life.
The Abcdes Of Melanoma
The first five letters of the alphabet are a guide to help you recognize the warning signs of melanoma.
A is for Asymmetry. Most melanomas are asymmetrical. If you draw a line through the middle of the lesion, the two halves dont match, so it looks different from a round to oval and symmetrical common mole.
B is for Border. Melanoma borders tend to be uneven and may have scalloped or notched edges, while common moles tend to have smoother, more even borders.
C is for Color. Multiple colors are a warning sign. While benign moles are usually a single shade of brown, a melanoma may have different shades of brown, tan or black. As it grows, the colors red, white or blue may also appear.
D is for Diameter or Dark. While its ideal to detect a melanoma when it is small, its a warning sign if a lesion is the size of a pencil eraser or larger. Some experts say it is also important to look for any lesion, no matter what size, that is darker than others. Rare, amelanotic melanomas are colorless.
E is for Evolving. Any change in size, shape, color or elevation of a spot on your skin, or any new symptom in it, such as bleeding, itching or crusting, may be a warning sign of melanoma.
If you notice these warning signs, or anything NEW, CHANGING or UNUSUAL on your skin see a dermatologist promptly.

What Does Scalp Melanoma Look Like
Melanoma is one of the most serious forms of cancer, and because its appearance can closely mimic natural moles, freckles, and age spots, it can be easy to overlook. Its important to know what to look for and perform regular skin cancer screenings to ensure you receive treatment for this condition in the earliest stages. According to Dr. Gregory Walker of U.S. Dermatology Partners in Waco, Texas, Melanoma can be easily overlooked in obvious places on the body, but many people dont know that the scalp, fingernails and toenails, and other harder to see areas often hide this condition until it has progressed to more advanced stages. Patients who know what to look for and regularly screen their skin for cancers, are much more likely to receive a diagnosis in early, more treatable stages. Keep reading to hear more from Dr. Walker about what scalp melanoma looks like and how to check for this condition and prevent serious health concerns.
What Does Skin Cancer Look Like On Your Face
Are you wondering what skin cancer looks like on your face? Is there a spot that is new or changing? For starters, let us just say kudos on paying attention! It is so vital to watch yourself for these things because early detection truly saves lives. Secondly, skin cancer has a variety of appearances so we will need to start by explaining exactly what skin cancer is and the types it can occur as.
What is Skin Cancer?Skin cancer is an abnormal growth of skin cells. It most often develops on areas of the skin exposed to the suns rays. Skin cancer affects people of all colors and races, although those with light skin who sunburn easily have a higher risk. Research has estimated that one in five Americans will develop skin cancer in their lifetime. According to the American Cancer Society, about 3.3 million basal and squamous cell skin cancers are diagnosed in America each year with an estimated 87,000+ new cases of melanoma predicted for 2020.
While rare types of skin cancer do exist, there are four main types of skin cancer:
Squamous cell carcinoma is the second most common type of skin cancer. SCC often appears as a red firm bump, scaly patch, or a sore that heals and then re-opens. SCC tends to form on skin that gets frequent sun exposure, such as the rim of the ear, face, neck, arms, chest, and back. Early diagnosis and treatment can prevent this and stop SCC from spreading to other areas of the body.

What Are The Signs Of Melanoma
Knowing how to spot melanoma is important because early melanomas are highly treatable. Melanoma can appear as moles, scaly patches, open sores or raised bumps.
Use the American Academy of Dermatology’s “ABCDE” memory device to learn the warning signs that a spot on your skin may be melanoma:
- Asymmetry: One half does not match the other half.
- Border: The edges are not smooth.
- Color: The color is mottled and uneven, with shades of brown, black, gray, red or white.
- Diameter: The spot is greater than the tip of a pencil eraser .
- Evolving: The spot is new or changing in size, shape or color.
Some melanomas don’t fit the ABCDE rule, so tell your doctor about any sores that won’t go away, unusual bumps or rashes or changes in your skin or in any existing moles.
Another tool to recognize melanoma is the ugly duckling sign. If one of your moles looks different from the others, its the ugly duckling and should be seen by a dermatologist.
A Primer On Skin Cancer
Malignant melanoma, especially in the later stages, is serious and treatment is difficult. Early diagnosis and treatment can increase the survival rate. Nonmelanoma skin cancers include basal cell carcinoma and squamous cell carcinoma. Both are common and are almost always cured when found early and treated. People who’ve had skin cancer once are at risk for getting it again they should get a checkup at least once a year.

The Five Stages Of Skin Cancer
Cancer in the skin thats at high risk for spreading shares features with basal cell carcinoma and squamous cell carcinoma. Some of these features are:
- Not less than 2 mm in thickness
- Has spread into the inner layers of the skin
- Has invaded skin nerves
In the earliest stage, cancer is only present in the upper layer of the skin. You may notice the appearance of blood vessels or a dent in the center of the skin growth. There are no traces of malignant cells beyond this layer.
At stage 1, cancer has not spread to muscles, bone, and other organs. It measures roughly 4/5 of an inch. Theres a possibility that it may have spread into the inner layer of the skin.
In this stage, cancer has become larger than 4/5 of an inch. Cancer still has not spread to muscles, bone, and other organs.
At stage 3, the cancer is still larger than 4/5 of an inch. Facial bones or a nearby lymph node may have been affected, but other organs remain safe. It may also spread to areas below the skin, such as into muscle, bone, and cartilage but not far from the original site.
Cancer can now be of any size and has likely spread into lymph nodes, bones, cartilage, muscle, or other organs. Distant organs such as the brain or lungs may also be affected. In rare cases, this stage might cause death when allowed to grow and become more invasive.
Melanomas That Could Be Mistaken For A Common Skin Problem
Melanoma that looks like a bruise
Melanoma can develop anywhere on the skin, including the bottom of the foot, where it can look like a bruise as shown here.
Melanoma that looks like a cyst
This reddish nodule looks a lot like a cyst, but testing proved that it was a melanoma.
In people of African descent, melanoma tends to develop on the palm, bottom of the foot, or under or around a nail.
Did you spot the asymmetry, uneven border, varied color, and diameter larger than that of a pencil eraser?
Dark line beneath a nail
Melanoma can develop under a fingernail or toenail, looking like a brown line as shown here.
While this line is thin, some are much thicker. The lines can also be much darker.

I’ve Been Diagnosed With Melanomawhat Happens Next
Doctors use the TNM system developed by the American Joint Committee on Cancer to begin the staging process. Its a classification based on three key factors:
T stands for the extent of the original tumor, its thickness or how deep it has grown and whether it has ulcerated.
What Is Breslow depth?
Breslow depth is a measurement from the surface of the skin to the deepest component of the melanoma.
Tumor thickness: Known as Breslow thickness or Breslow depth, this is a significant factor in predicting how far a melanoma has advanced. In general, a thinner Breslow depth indicates a smaller chance that the tumor has spread and a better outlook for treatment success. The thicker the melanoma measures, the greater its chance of spreading.
Tumor ulceration: Ulceration is a breakdown of the skin on top of the melanoma. Melanomas with ulceration are more serious because they have a greater risk of spreading, so they are staged higher than tumors without ulceration.
N indicates whether or not the cancer has already spread to nearby lymph nodes. The N category also includes in-transit tumors that have spread beyond the primary tumor toward the local lymph nodes but have not yet reached the lymph nodes.
M represents spread or metastasis to distant lymph nodes or skin sites and organs such as the lungs or brain.
After TNM categories are identified, the overall stage number is assigned. A lower stage number means less progression of the disease.
When To See A Doctor About Skin Cancer
Many people, especially those who have fair coloring or have had extensive sun exposure, should periodically check their entire body for suggestive moles and lesions.
Have your primary healthcare professional or a skin specialist check any moles or spots that concern you.
See your healthcare professional to check your skin if you notice any changes in the size, shape, color, or texture of pigmented areas .
If you have skin cancer, your skin specialist or cancer specialist will talk to you about symptoms of metastatic disease that might require care in a hospital.
